The Historic city of Yazd in Iran, recognized as a World Heritage Site by UNESCO, is an outstanding example of how Ancient Civilizations implemented Nature Based Solutions in their Architecture. Before fossil-fuel-powered air-conditioning was available, people living in harsh climates had nothing but natural means to control the interior temperature. Because of generations of adaptations to its desert surroundings, the city has developed one of the world's most innovative nature-based air-conditioning systems. Their system was so well engineered that it is still working today after thousands of years. So how does it work? Wind Towers, also known as Wind Cathers or Badgir (in Farsi), were engineered to catch the cool breeze from higher altitudes. The towers are connected to an underground ventilation network, where the air is cooled down naturally to comfortable indoor temperatures before entering the buildings. This is possible because the temperatures under the ground are much lower than above ground. This system operated so well that it later evolved to produce and store ice in the desert without consuming energy. Read Full Article here:

        @marine_stephan It sure is interesting, we have been using this design solution in all our projects during the past decade. There are also other projects around the world that have implemented this solution very successfully.
